I am brand new to the physics forum community, so let me start off by saying hello to everyone. I am interested im coming up with a matlab code for orbit determination. I saw a thread recently discussing this type of topic but i think it was orbit determination using RA and Dec measurements only. I was thinking more along the lines of using a given .TLE file (Two Line Element) and going from there. This said, i am not too familiar with TLE's or how they are used. Any help would be appreciated as well as any example matlab codes as i am not greatly proficient with MATLAB or any other language for that matter. Thanks guys!!
